The 2013 Continental GT Speed Convertible is finally getting the mid-cycle update that other Continental GT models have already benefited from. Shown this week at the 2013 Detroit Auto Show, we took a moment to detail these changes on video.

The update is merely a mid-cycle, but the changes are significant. The styling is slightly sharper and the interior has been revised, but the largest changes are in the engine bay and under the metal.

You'll reach 60 from a stand still in only 4.1 seconds thanks to an extra 16 horsepower and 37 pound-feet of torque. Fuel economy has improved by 15 percent with new ratings expected to be 12 mpg in the city and 15 mpg on the highway, which will equal a 15 mpg combined rating.

The engineers have increased the width of the track and sharpened up the steering. All-wheel drive settings have more rear-biased dialed in, and the suspension has been lowered 10 millimeters.

Bentley's upgraded the infotainment system with its latest software with even more points of interest, optional satellite landscape imagery, live traffic data, and in some places, a digital radio.
